Discount percent = 33%
Sale price = $268
Let the original price be $x.
So,
So, yesterday the price was $400.
y = (2x-4)/3
to find the inverse change x and y then solve for y
x = (2y-4)/3
mutiply by 3 on each side
3x = 2y-4
add 4 to each side
3x+4 =2y
divide by 2
(3x+4)/2=y
h^-1 (x) = (3x+4)/2
Choice C
7 +5x= -18
5x= -25
X= -5
B) one solution
C) i think it is : ( 14 + 10(-5))/ 12 = -36/ 12= -3
Given:
Height of man = 6 ft
Height of man's shadow = 11 feet
Height of building's shadow = 139 feet
To find:
The height of the building.
Solution:
We know that the heights of the objects and there shadows are always proportional.
Let x be the height of the building.
Multiply both sides by 139.
Therefore, the building is 75.8 feet long.
Answer:
x = 31
Step-by-step explanation:
13 + 6 + 2x - 18 = 4x - 29
1 + 2x = 4x - 29
30 + 2x = 4x
30 = 2x
15 = x
4(15) - 29
60 - 29
31 is the unknown measurement
